a mildly disgruntled Church of Satan member on YouTube. He says he's been a member for 15 years, but has issues with certain aspects of the Church of Satan, all of which I find to be very misguided.

I don't get the idea of a "mildly disgruntled Church of Satan member". If being a CoS member isn't pleasurable, why be one? If they have issues worth complaining about, why subject themselves to it at all? Even if they're not misguided, even if every gripe is legit, why bother unless the good outweighs the bad?
